I built with the default options with command ./configure. I tried looking
the options, but there is no specific options in the list to compile with
the controls and extended features.

I am trying to test
the controls functionality of my LDAP client for the controls and am not
able to get those on my server.

Which controls is implemented in your client?

I have not added any controls in my client (yet!!! I am not aware if the
LDAP client too needs to implement the controls) I am tring with Softerra
LDAP browser to see which controls are available on the server. SOfterra
shows all the supported on the openLDAP and does not show any on my
installation.

Please hint me as for a newbie as to how can I get these available on my
openLDAP server.

Be more precise in you what you're asking and surely someone will help
you.

I am trying to write my own LDAP client for simulating multi queries and
users for performance test on the LDAP server. I have written the basic LDAP
command functionality part and controls for all the commands with basic
syntax as mentioned in the RFC -

To check if these are working on my scripts I need to configure these on my
openLDAP server. Possibly all the available controls. I am facing problem in
getting this control and extended functionality available on my server.There
are not many books or online resources (that I could find) with reference to
these features :(
